ERNEST JAMES HISCOCK, OF HYTI-IE, ENGLAND.

MAGAZINE FOR MINIATURE AMMUNITION FOR RIFLES.

Application filed December 30, 1912.

To all whom it may concern:

Be it known that I, Ermnsr JAMns Hrs- COCK, a subject of the King ofGreat Britain, residing at the School of Musketry, Hythe, Kent, England,have invented a new and useful Magazine for Miniature Ammunition forRifles, of which the following is a speci fication.

My invention has for its object to provide means whereby fire armshaving a bolt action, such, for instance, as the rifle known as the Leemagazine rifle, and which have been converted for use with .22 inch rimfire cartridges or other miniature ammunition, for firing practice atminiature rifle ranges, instead of being loaded by hand, can beautomatically loaded by the operation of the bolt, thereby permitting ofrapid firing.

According to the invention I provide a detachable magazine which isdesigned to be introduced into the ordinary magazine chamber in therifle, and which isso arranged that the cartridges will be pushed fromthe magazine by the ordinary bolt adapted, for say, .303 inch or otherammunition such as is now generally used in a service rifle.

The magazine constructed according to my invention is provided with acase for containing the miniature ammunition and with a spring chargingplunger carried on a platform or body part and adapted to be engaged bythe rifle bolt, the said body part being constructed so that when thesaid plunger has been pushed forward to inserta cartridge into thechamber of the rifle, the whole of the magazine will be depressed so asto allow the bolt to pass above the same to force the cartridge homeinto the chamber and support it during firing.

My invention will be readily understood by reference to the accompanyingdrawing, in which Figure 1 is a sectional view of my improved magazine,Fig. 2 a plan, and Fig. 3 a front view thereof. Fig. 4 is a sectionalside view showing the improved magazine applied in the magazine chamberof the gun, the breech being open, and Fig. 5 is a similar view showingthe breech closed and the magazine depressed.

a indicates the case or magazine proper in which the miniatureammunition is stored, the said case being preferably made by bending aplate of sheet steel around a mandrel and brazing the adjacent edges onthe rear side, a strengthening strip 6 being Specification of LettersPatent.

provided around the upper part. This case, which is advantageouslyadapted to contain 10 cartridges, has within it a spring 0, which at thelower end bears upon a plate (Z, the said plate being made removable soas to allow of inserting the spring and removing it when required. Atthe upper part of the magazine the lateral walls are bent over to formstops 6, e, 6 6 for retaining the cartridges in the magazine against thepressure of the spring 0, when charging the magazine, and alid 7 ispivoted to the top of the case to support the cartridges as they arepushed from the magazine through the hole 7.

g is the body portion of the magazine which is preferably made of caststeel and drilled or recessed to receive a plunger it preferably also ofcast steel which is surrounded by a spring a to normally hold theplunger in a position with its head against a stop screwed into thebody. The body 9 is brazed or otherwise firmly fixed to the case a sothat the plunger it can pass through a hole 70 in the latter, oppositeto the hole f in order to push the uppermost cartridge out of the case athrough the hole F.

The case a with the body 9 is designed to be inserted into the usualmagazine chamber of the rifle in the manner shown in Fig. 4, a steelspring Z of zig-zag or other suitable form being placed in the saidchamber beneath the body 9, and serving to normally press the magazineas a whole upward, a stop a secured to the case a bearing against theunderside of a plate a brazed into the trigger guard of the rifle in amanner clearly shown in Fig. 4. The upper surface of the body 9 isformed with inclines 0, 0 and is cut away at the rear of these inclinesin such a manner that the upper part of the plunger h is uncovered sothat the bolt m will engage with it as will be clearly understood byreference to Fig. 4. With this arrangement when the magazine is chargedand the breech of the gun is open as shown in Fig. 4, the breech bolt mwhen pushed forward will come into contact with the plunger h and pushthe latter into the magazine case, and at the same time push therefromthe uppermost cartridge through the hole 7' so that the front portion ofthe cartridge enters the chamber 1?, until within about 3; of an inch ofbeing pressed home, the remaining cartridges being pushed up by thespring a. As the forward movement of the bolt m is continued the latterby coming into contact with the inclines 0, 0 of the body releases theplunger k and pushes the whole magazine downward so that the bolt passesover the same and pushes the cartridge home into the chamber, as clearlyshown in Fig. 5, while at the same time the plunger it moves rearwardlyunder the ac tion of its spring. After the cartridge in the barrel hasbeen fired the bolt 7% is pulled back to extract the empty cartridgecase the rim of which comes into contact with an upstanding lug orprojection on the body 9 and V is thereby disengaged from the "usualextractor (not shown) on the bolt and 1. A magazine for miniatureammunition for a converted bolt rifle provided with a plunger forpushing the cart-ridges from the magazine designed to be operated by thebolt and adapted to be depressed to allow the bolt to pass over it,substantially as described.

2. In a magazine for miniature ammunition for converted bolt rifles thecombination with a case or chamber for containing the ammunition, of abody part fixed to the said case, a plunger sliding in the body part anddesigned to be acted upon by the bolt of the rifle for pushing theuppermost cartridge through the case, a spring for supporting the bodyand case and means whereby the bolt of the rifle when pushed forwardwill push in the said plunger and depress the magazine, substantiallyas, and for the purpose, described.

8. A magazine for attachment to bolt rifles converted for use withminiature ammunition, comprising a case for containing the cartridges, aspring supported bodypart fixed to the said case, a spring plunger andan inclined part to engage the breechbolt to depress the magazine, afterthe cartridge has been forced out by the plunger, substantially asdescribed.

t. The combination with a magazine for attachment to bolt riflesconverted for use with miniature ammunition of a lug on the magazinedesigned to eject the empty cartridge case when the bolt is withdrawn,substantially as described.
